To all whom it mayroncrn:

Be 1t known that I, WILLIAM A. LoUDoN, a

citizen of the UnitedStates, residing at Chi-4 cago, in the county'ofCook and State-of Illinols, have invented anew and useful AutomatlcTurbine, of' which the following is a specification.

Myinvention relates to turbines, which arel provided on their eripheryWith a plurality of buckets or poc ets intowhich fluid is forced at atangent, and the o jectsof my improvement are first, toautomaticallydecrease-or increase the size or area of the` buckets Aas the vspeed ofthe turbine may require-while 1t 1n action, second, to so connect themovingy parts in the buckets that they will allmove-in unison; third, tocon- `the buckets and when the turbine attains the n desired speed thebuckets are automaticallyl decrease in capacity so as to retain the-des'ir'ed speed. It is immaterial in what manner this regulation of thearea or capacityv of the buckets is accomplished, and I have shownseveral modifications. v

Another modication not shown may be v made by constructing two disks orwheels adjacent to each other and provided with intermeshing teeth insuch manner that by shiftin the wheels with relation to each other tpockets orbuckets formed between the teeth of the wheels are variedv inarea or Vo describe my invention so that others versed inV the art towhich it pertains can understand it suiiiciently to make and use thesame, I have illustrated `it on the accompanying sheet of vdrawing inwhich:

Figure 1 is -a fragmental cross sectional view through a turbineembodyin my invention; Fi ..2 is a detail sections. View of a ig. 3 is asimilar View to Fig. 1, of a modication;'Fig. 4 isla similar View ofanressurey other modification and Fig. v5 is a sin'iilar view of stillanother modification. l

l Similar reference characters refer to similar arts throughout theseveral views.

eferring toig. 1 and 2, the steam chest 6 is secured to the casing 7,within which is mounted to rotate about the shaft 8 the turbine wheel 9.The periphery of the wheel 9 is provided with a plurality of pockets10,. into which the steam from the steam chest 6 is discharged throughthenozzles 11. Movably mounted in each pocket 10 is a piston orpartition 12 secured to a pin 13 extending through a hole providedtherefor in the rim of the wheel 9 which pin has on its exposed 415, soas to normally hold the piston 12 in against the bottom of the pocket10, thus leaving the' open end of the pocket unobstructed to the actionof the steam from the nozzles 1 1.

All the springs 15 are adjusted, by turning the nuts 14, to resist theradially outward pull, caused by the centrifugal force on the pistonsand Atheir connections, until a desired` speed .of thewheel 9isattained. Should the Wheel 9 for any reason tend to revolve fasterthan the desired speed the centrifugal force of the pistons willovercome the force of the springs and will move radially outward in thepockets, thus partially or totally obstructing the open end of thepockets, which will act t'o decrease the speed ofthe wheel 9 because thesteain from the nozzles 11 will be artially or totally prevented from'enteringtiie pook'- ets 10.

It will be understood that an intermediate position of the pistons 12will act as a control over' the wheel 9 and the .full outer position ofsaid pistons Would act to stop the Wheel entirely, by closing theentrance to the pockets.

To prevent any possibility of the pistons 12 movin out beyondtheperipheral surface Vof the w eel 9, I preferv to have the side lianges16'of the wheel provided with the cilL cumf'erential rim 17 which willserve as a stop for the pistons.

In Fig. 3, the exposed ends of the pins 13 are shown as being pivotallyconnected to one arm' of a bell-crank lever' 18 which is pvoted tothewheel 9 at 19. The other arm of the bell-crank lever 18 is pivotallysecured to a iioating ring 2() which is normally pulled by a spring 21in such direction asto I swings about the pivot 38, by reason. of theholdlthe pistons-12 down the bottom ofthe y pockets 10.

, periphery of the Wheel. f The'disk 22 'is'pr -vided With an eccentricpin 24 which isenin Fi .4, interposed @miser et@` ins ..13 are shown asbein connected to a isk 22 pivoted about the shaft 8 by-conneo rods 23in such manner thatthe of the.. -4 i 'ullthepistons'iZ in'toward thebottoms o the ockets4 andv turning the disk in anopposite irectionwill.disk in one direction will allow the pistons to move out toward' thegaged'by the forked arm of a-bell-crank'lever 25 pivotedto the Wheel 9at 26 and having its other arm 4providedjwith a Weight 2,7, so.

periphery With pockets having the lids 31 which are pivoted at 32 andeach is provided With an arm^33 extending throu ha slot providedtherefor in the rim of t e Wheel 29.. The free end of each arm 33-restsin a recess 34 rovided in a ring 35. The ring 35 is provi ed with one ormore pins 36'Which are engaged by the slotted arm of a bellvcrank .lever37'- pivoted to the vvheel 29 at -38 and having its other arm providedWith a Welght 39, in such manner thatwhen the Weight 39 centrifugalforce createdby the rotation ,of ythe Wheel 29, the bell-crank lever 37will .move the ring 35 so'as tovswing the lids 31 across `the open endof the pockets 3() and thus decrease the size of .the Dockets exposed tothe blast of'steam from the nozzles 11.

Y The movement ofthe Weight 39 is controlled by a'spring 40.

increasing the area vof ther pockets exposed tothe jets of steam arecapable of radical' change from the. constructions shovvn'without" inthe Yleast the invention.' l Havin Ithus fully v what I c aim .as newanddesire-to secure by Letters Patent vof the United States isY: -l
